I'm looking at getting a 180 SR oil filter bracket, the one without the heat exchanger (see pic below).

I'm running the tomei adapter to a filter relocator at the moment and it's a pain in the ass to be honest, I wanted to get rid of the huge heat exchanger and that was the only solution I knew at the time. I have kilometers of oil piping and the relocator is not extremely well fitted to it's position and blahblah problems.

I was just wondering if there is anything to consider when using this bracket. For example the screw on the side, is it a thermostat or a pressure regulator? if it's a pressure reg, should I remove it in the S14 SR? etc.

Thanks in advance for any help!
